Chassis
The Dallara IR-01 features a simplified suspension design which forgoes
dedicated springs for each corner of the car, as you would see in a road
car or most other race cars. Instead, heave (pitch) and roll are handled
independently via front and rear Heave Springs and Anti-Roll Bars,
respectively. Aerodynamic performance can be tuned via the Heave Springs
to maintain an efficient aerodynamic platform, while the chassis roll and
overall mechanical balance can be tuned via the Anti-Roll Bars.
FRONT
ARB STIFFNESS
The ARB (Anti-Roll Bar) stiffness setting adjusts the roll stiffness of the front suspension via a change in the ARB’s diameter.
Increasing the ARB stiffness will increase the roll stiffness of the front suspension, resulting in less body roll but increasing
mechanical understeer. This can also, in some cases, lead to a more responsive steering feel from the driver. Conversely,
reducing the ARB stiffness will soften the suspension in roll, increasing body roll but decreasing mechanical understeer. This can
result in a less-responsive feel from the steering, but grip across the front axle will increase.
